PURPOSE:To easily insert a pin into a hole of branch elements, by devising shape of a hole diameter of the branch elements and shape of the pin fitted to said branch elements in a coupling used for control linkages of a vehicle speed change gear. CONSTITUTION:A coupling, for connecting a control rod 10 and stricking rod 14, is constituted by branch elements 12, 13, secured to the connection end of each rod 10, 14, and a connecting element 15 connecting the both branch elements 12, 13 through a pin 16. The connecting element 15 is constituted by binding two cylindrical members 15a, 15b, fitted with a bush 17 respectively, to cross shape. In such a coupling as in the above, a major contoured hole 13a and minor contoured hole 13b are formed coaxially in extended protrusive parts 13c axially of the branch element 13 (same for 12). Further a large contour part 16e, fitted to said major contoured hole 13a, is formed to the pin 16 in its portion neighboring to its head part 16b in its shaft part 16a, and a screw part 16c is successively provided in its lower end. |
